By reusing we can reduce municipal wastage and reduce environmental strain.

Multiple choice importance of waste disposal need and method for reducing, reusing and recycling waste geography

Consumers are encouraged to reduce their waste by 

  1. Switching to re-useable

  2. Buying items with less packaging

  3. Purchasing in bulk

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

It is always necessary to reduce the waste to keep environment safe from pollution

It can be achieved by many ways. Some of them according to the options given are

Switching to reusable products like milk bottles instead of packets so that the bottles can be used multiple times, reducing municipal waste.

Buying items with less packaging as it obvious that more packaging produces more wastage.

Buying bulk products is another important solution to reduce waste because individual packing requires more packaging when compared to bulk packaging.

D Correct answer
Explanation

Plastic in today's world plays a very important role in day to day life. They are most commonly used as polythene bags (carry bags). Also they are used in food industry for packaging as wrappers, tetra packs for milk etc. Plastics can be good thermal insulator. Hence, can be used to coat all the electrical appliances.

  2. Bring your own to-go mug with you to the coffee shop

  3. Say no to single serving packaging, buy in bulk and share with friends instead

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The best thing we can do to protect our waterways is try to keep as much plastic as possible out of the waste stream in the first place. There are many small ways you can have a big impact.

1. Wean yourself off disposable plastics.
Ninety percent of the plastic items in our daily lives are used once and then chucked: grocery bags, plastic wrap, disposable cutlery, straws, coffee-cup lids. Take note of how often you rely on these products and replace them with reusable versions. It only takes a few times of bringing your own bags to the store, silverware to the office, or travel mug to Starbucks before it becomes habit.
2. Stop buying water.
Each year, close to 20 billion plastic bottles are tossed in the trash. Carry a reusable bottle in your bag, and you’ll never be caught having to resort to a Poland Spring or Evian again. If you’re nervous about the quality of your local tap water, look for a model with a built-in filter.
3. Boycott microbeads.
Those little plastic scrubbers found in so many beauty products—facial scrubs, toothpaste, body washes—might look harmless, but their tiny size allows them to slip through water-treatment plants. Unfortunately, they also look just like food to some marine animals. Opt for products with natural exfoliants, like oatmeal or salt, instead.
4. Cook more.
Not only is it healthier, but making your own meals doesn’t involve takeout containers or doggy bags. For those times when you do order in or eat out, tell the establishment you don’t need any plastic cutlery or, for some serious extra credit, bring your own food-storage containers to restaurants for leftovers.
5. Purchase items secondhand.
New toys and electronic gadgets, especially, come with all kinds of plastic packaging—from those frustrating hard-to-crack shells to twisty ties. Search the shelves of thrift stores, neighborhood garage sales, or online postings for items that are just as good when previously used. 
6. Recycle (duh).
It seems obvious, but we’re not doing a great job of it. For example, less than 14 percent of plastic packaging is recycled. Check out the number on the bottom of the container. Most beverage and liquid cleaner bottles will be #1 (PET), which is commonly accepted by most curbside recycling companies. Containers marked #2 (HDPE; typically slightly heavier-duty bottles for milk, juice, and laundry detergent) and #5 (PP; plastic cutlery, yogurt and margarine tubs, ketchup bottles) are also recyclable in some areas. 
7. Support a bag tax or ban.
Urge your elected officials to follow the lead of those in San Francisco, Chicago, and close to 150 other cities and counties by introducing or supporting legislation that would make plastic-bag use less desirable.
8. Buy in bulk.
Single-serving yogurts, travel-size toiletries, tiny packages of nuts—consider the product-to-packaging ratio of items you tend to buy often and select the bigger container instead of buying several smaller ones over time.
9. Bring your own garment bag to the dry cleaner.
Invest in a zippered fabric bag and request that your cleaned items be returned in it instead of sheathed in plastic. (And while you’re at it, make sure you’re frequenting a dry cleaner that skips the perc, a toxic chemical found in some cleaning solvents.)
10. Put pressure on manufacturers.
Though we can make a difference through our own habits, corporations obviously have a much bigger footprint. If you believe a company could be smarter about its packaging, make your voice heard.
